A woman who joined her teenage daughter in attacking her daughter's ex-boyfriend in Allentown gave up her right to a preliminary hearing on Friday and will face trial in Lehigh County Court.

Tasha Fofano, 34, of Allentown, is charged with aggravated assault, simple assault, criminal trespassing and conspiracy. She waived her hearing Friday before District Judge Wayne Maura who also refused to lower her $75,000 bail.

Fofano's 17-year-old daughter Raedawn S. Mayo allegedly slashed her ex-boyfriend's neck and chest with a box cutter during the Nov. 12 assault in an apartment in the 1300 block of Walnut Street, according to court records. Jermain Davis needed nine stitches to repair his injuries.

Mayo was charged with attempted homicide and related charges. Last month, Maura ruled enough evidence existed to send her case to trial.

Allentown police said Fofano, Mayo and Mayo's aunt went to an apartment where Davis was living with his new girlfriend and forced their way inside.

Fofano and Mayo attacked Davis while the aunt tried to get them to leave, police said.

According to court records, Fofano admitted being in the home, but couldn't say if she hit anyone because of "blacking out" during the alleged assault. Mayo allegedly slashed Davis with the box cutter after seeing him push her mother, police said.

Mayo said their relationship with Davis was abusive and he continued to harass her in text messages, so she went to his home to get him to stop, police said.

Davis was also charged that day. Allentown police said they found cocaine and packaging material inside the home.
